What's the status of the Ålstensskogen–Storskogen Nature Reserve?

Environment Bromma
Current status
Reserve in force – nearby land allocation still contested and undecided
  • The City Council decided on 13 April 2026 to establish the Ålstensskogen–Storskogen nature reserve in southeastern Bromma, and the decision gained legal force on 13 May 2026. 1 2
  • The reserve covers Storskogen north of Alviksvägen and Ålstensskogen, Ålstensängen, Solviksängen and Solviksbadet to the south, within the boundary described in the statement and adopted by the decision. 1 2
  • A land allocation for about 50 rental apartments at Ålsten 1:1, outside the reserve, remains politically contested: a motion to cancel it instead and expand the reserve with subareas 25 and 44 has not received a final City Council decision in the available sources, and the matter is on the Council's agenda for 21 September 2026. 1 2 3 4

What is protected

  • The reserve's purpose is to preserve biological diversity and protect valuable nature and cultural environments long-term, and to preserve and provide access to the area for outdoor recreation, leisure and public health, in line with the purpose described in the statement and adopted by the decision. 1 2
  • The management plan prioritizes ongoing care of pine forests and culturally shaped broadleaf environments, along with measures for bats, amphibians and control of invasive species. 1
  • Visitors can continue to walk, run, swim, exercise, play, rest, pick berries and mushrooms, and have picnics in the area, but it is prohibited to fell or damage trees, collect dead wood, damage rock, soil or stone, light fires outside designated spots, or disturb wildlife. 1
  • The proposed area was given as about 67.2 hectares, of which about 19 hectares is water and about 100 metres extend into Lake Mälaren, in the statement ahead of the decision; the city's project page stated in September 2026 that the established reserve covers about 67.7 hectares. The sources do not explain the difference between the two figures. 1 2

What is outside the reserve

  • Subarea 25, located between the Smedslätten tennis courts and Solviksängen, was left outside the boundary described in the statement and adopted by the decision. The Moderates, Sweden Democrats, Liberals, Centre Party and Christian Democrats objected and wanted the area included in the reserve. 1 2
  • A later motion from Johan Paccamonti (M) proposed that subarea 44 also be included in the reserve, along with area 25; the proposal has not led to a changed reserve boundary in the available sources. 1
  • An area lying outside the nature reserve does not mean development there is approved. Questions about nature values, recreation and the surrounding environment are, if applicable, further assessed in the forthcoming detailed development-plan process. 1 2

What is proposed or undecided

  • The City Real Estate and Traffic Committee (Exploateringsnämnden) decided on 11 December 2025 to allocate land within the Ålsten 1:1 property, outside the nature reserve, to Svenska Bostäder for about 50 rental apartments in the form of Stockholmshus. 1
  • The City Planning Office has issued a positive planbesked to assess the possibility of starting planning work at Alviksvägen. A planbesked is only an assessment of the possibility of starting planning work — the final assessment of the land's suitability takes place during the planning work itself. 1
  • One political statement in the case mentions a possible larger tennis hall at the site alongside the planned housing, as an idea linked to the land allocation, not as a separately decided project. 1
  • Johan Paccamonti (M) put forward a motion to cancel the Solviksängen land allocation and instead let subareas 25 and 44 become part of the nature reserve. The City Executive Board decided on 27 May 2026 to propose to the City Council that the motion be considered answered with reference to the statement — this is a proposal to the Council, not a final Council decision. The matter is on the City Council's agenda for the meeting on 21 September 2026, and the sources contain no later Council decision on it. 1 2 3
  • Johan Paccamonti (M) has also put forward a separate motion for a protection program for Bromma's green areas (KS 2026/468), which cites Ålstensskogen as an example of the underlying policy tension. The Environment and Health Committee approved the administration's referral response on 25 August 2026 (the Moderates dissented, wanting to endorse the motion instead), and Bromma District Council is expected to consider its own referral response on 24 September 2026. A reply to the City Executive Board is due by 16 October 2026. The motion is a separate, still-undecided matter and does not change the decided reserve boundary or the Solviksängen land allocation. 1 2

Why is this happening?

The case reflects a balance between the city's goal of protecting the high nature and cultural values of Ålstensskogen–Storskogen long-term, as described in the statement and decision, and the city's budget mandate to create more rental housing in southern Bromma, mentioned in the response about the development plans. That tension is clearest in the Solviksängen land allocation, which sits outside the decided reserve boundary. 1 2 3

What happens next?

The City Council has the Solviksängen motion on its agenda for the meeting on 21 September 2026; the outcome is not known in the available sources until that meeting has been held and the minutes published. The Ålsten 1:1 housing project is further assessed in the forthcoming detailed development-plan process, including public consultation. 1 2

    Protecting nature and building homes in Bromma

    The Moderates are questioning why parts of Ålstensskogen and Storskogen in Bromma are excluded from a new nature reserve, fearing these areas are instead slated for large-scale, non-transparent development. They specifically ask about the planned construction and why this information is withheld from residents. City Planning Commissioner Jan Valeskog (S) confirmed that while a 67.2-hectare nature reserve is established, the Exploitation Committee has allocated land for approximately 50 new rental apartments (Stockholmshus) to diversify housing in southern Bromma, asserting that the process is open and democratic, with public input opportunities during detailed planning.

    Protecting Bromma's forests and public access to nature.

    Stockholm City Council plans to establish the Ålstensskogen and Storskogen nature reserves in southeastern Bromma, a 67.2-hectare area including Solviksbadet. The aim is to protect its high natural and cultural values, such as old-growth forests and bats, while ensuring continued access for recreation and outdoor activities.

    Protecting Bromma's forests and public access to nature.

    The City of Stockholm plans to establish the Ålstensskogen and Storskogen nature reserves in Bromma, covering about 67.2 hectares including Solviksbadet. This proposal aims to protect the forest, its high natural values, cultural environment, and secure public access for recreation, bathing, and outdoor life. While the proposal was slightly adjusted after a minority referral, several parties (M, L, SD, C, KD) have criticized the proposed boundaries, arguing that additional areas with natural values, particularly area 25, should be included in the reserve instead of potentially being developed.

    Forest garden in Skogsbo: Council files citizen proposal

    The Bromma City District Council reviewed a citizen proposal to establish a community-based forest garden in the Skogsbo area of Ålsten. The council approved the administration's statement, meaning the proposal was filed without further action. The district administration cited a lack of resources and current mandate to handle the proposal, along with outstanding issues such as the formation of a nature reserve, an upcoming program for urban farming, and discussions with the property management office.

    Councillor Johan Paccamonti (M) questioned Jan Valeskog (S), Commissioner for Urban Development and Sport, about "secret" building plans at Ålstensskogen and Storskogen, expressing concern that a large green space was excluded from theigned nature reserve, potentially leading to large-scale development.

    Stop Solviksängen Development, Protect Green Space

    The City Executive Board rejected a motion from Johan Paccamonti (M) to halt building plans at Solviksängen in Bromma and instead include the area in the Ålstensskogen and Storskogen nature reserves. The motion was denied because the building plans align with the city's master plan for creating more rental apartments in southern Bromma, and environmental values will be further investigated during the detailed planning process. The Moderates and Liberals dissented, advocating for the protection of the green space.

    Stop Housing Development at Solviksängen and Protect the Forest Areas

    The motion proposes cancelling the land allocation for housing at Solviksängen along Alviksvägen and including areas 25 and 44 in the Ålstensskogen and Storskogen nature reserve. Instead, it proposes building new rental housing in Bromma within larger areas that have already been developed, such as Alviks strand, Brommadepån and Linta Gårdsväg, where more than 2,000 homes are planned. However, the city administrations assess that the site could be considered for around 50 homes, with its natural and recreational values to be investigated further during the detailed planning process.

    Review Stockholm housing goals, halt projects like Ålstensskogen, Nälsta ängar

    The Committee for the Elderly decided to adopt the administration's statement in response to a referral from the City Executive Board.

    The motion proposes revoking the land allocation for housing at Solviksängen along Alviksvägen and instead including areas 25 and 44 in the Ålstensskogen and Storskogen nature reserve. The City Executive Office, the Real Estate Committee, and the City Planning Committee propose that the motion be considered answered, as the site could be assessed for approximately 50 rental homes and issues concerning nature, recreation, and the local environment will be investigated in the detailed development plan; the proposer instead wants to concentrate housing construction in Bromma on already developed areas such as Alviks strand, Brommadepån, and Linta Gårdsväg.

    Bromma green spaces: Motion for protection program rejected

    Bromma District Administration proposes that the committee submit a consultation response to the City Executive Board regarding the Moderates’ motion for a protection programme for Bromma’s green areas. The motion calls, among other things, for protecting Area 25 at Solviksängen and Myrberget in Traneberg, building more on industrial land instead of natural areas, and investigating how much new construction the traffic system can handle; the administration supports using land that has already been paved or developed, but notes that former industrial land may be contaminated and require extensive remediation. The administration also agrees that schools, preschools and other public services should be planned together with new development.
